This is a regular dictionary that allows you to define it with type hints, allowing for better documentation of simple objects like dictionaries. To use them, create a class that inherits from `typing.TypedDict` and define your expected keys and their types like so: ```python from typing import TypedDict class ModelMetadata(TypedDict): audience_id: str training_correlation: List[float] validation_correlation: List[float] final_sample_count: int final_accounts: List[AccountMetadata] ```
